I have a customer at my store who is fanatical about this subject. He has a radiation detectors around his house, Geiger counter I believe, and tracks the levels day to day that he claims are coming from Japan. He will not buy any food from there or the west coast and restricts when his family is allowed to venture outside due to fluctuating levels. Is he nuts? I don't know I hope so, if not F**k this sucks.
